This Early Access game is currently not a finished game and may or may not change significantly over the course of development. GamersGate don't guarantee that the game will be released as a full game, that is up to the publisher/developers.
When will these games release?
Its up to the developer to determine when they are ready to 'release'. Some developers have a concrete deadline in mind, while others will get a better sense as the development of the game progresses. You should be aware that some teams will be unable to 'finish' their game. So you should only buy an Early Access game if you are excited about playing it in its current state.
CAUTION: THIS GAME IS STILL IN ACTIVE DEVELOPMENT. PLEASE DO NOT PURCHASE UNLESS YOU WANT TO PARTICIPATE IN THE FEEDBACK AND DEVELOPMENT OF THE GAME. PLAYERS SHOULD EXPECT INCOMPLETE GAMEPLAY DURING THE EARLY ACCESS PROCESS.
